The Prefix WhoIs Project

The Prefix WhoIs Project provides a whois-compatible client and server framework for disclosing various up-to-date routing and network/security-related information. Instead of using registrar-originated network information (which is often unspecific or inaccurate), Prefix WhoIs uses the Internet's global routing table as gleaned from a number of routing peers around the world. The Prefix WhoIs project also operates a global network of public servers running a derivative of our Prefix WhoIs Server software. 100% of our network resources (servers, network transit, etc.) have been donated by public or private organizations. Many of our servers are operated by large Internet Service Providers.
